Germany started out as a loosely federated collection of individual states with names like Baden, Bavaria, Oldenburg, and Saxony. In 1871, Otto Von Bismark from the German state of Prussia, unified most of the states into a single German Empire. This empire lasted until 1917, when it was defeated during World War I.
The old German Empire minted these 25 pfennig coins between 1909 and 1912. The coins are made of nickel, not silver, so they have no bullion value. Collector values run like this for most dates (better dates are shown below):
worn: $3 US dollars approximate catalog value
average circulated: $10
well preserved: $22
fully uncirculated: $80
coins dated 1910A, 1911A, and 1912A are quite common and are worth about one-half of these values.
There are a few better dates in the series. The values shown below are for coins in well preserved condition:
